Solutions innovantes pour réaliser des lasers à impulsions ultra-brèves stable et fiable, pour application industrielles (SIRIUS)

The main objective of the SIRIUS project was the development of a new all-fiber passive mode-locked laser. The proposed lasers are based on the nonlinear polarization evolution occurring during the propagation along lon spans of PM fiber. We studied both numerically and experimentally the operation of different cavity designs in various pulsed and dispersive regimes. A deep understanding of the cavity enabled to design low repletion rate laser sources while sustaining picosecond pulses duration at 1 µm wavelength in a fully reliable and reproducile way.
